Add gst-recorder implementation for weston2.0.0
This commit support virtual display and gst-recorder function for weston2.0.0. It is update patch for weston 2.0.0 and based on 562c0c1bb2ef74ccbfda1bae4f84a61828119674 Virtual display is additional display like as offscreen buffer and it is created from drm-backend. The gst-recorder is a transfer system using H.264 streaming and Ethernet. Change-Id: I1e1b07701229d47ab6616e85d78c6aa039a0775b Signed-off-by: Harunobu Kurokawa <harunobu.kurokawa.dn@renesas.com>

+Subject: [PATCH 1/4] Add virtual output support
+
+This patch is ported to weston 2.0.0.
+
+----------
+Author: Damian Hobson-Garcia <dhobsong@igel.co.jp>
+Date: Thu Apr 27 16:47:00 2017 +0900
+
+Following patch ported to Weston 1.11 with minor updates
+ ----------
+ Author: Grigory Kletsko <grigory.kletsko@cogentembedded.com>
+ Date: Wed Nov 2 17:14:43 2016 +0300
+
+ To enable virtual output set "virtual" property in core section
+ to desirable number of virtual outputs. Then add settings to
+ each virtual output in output sections. Name of the outputs
+ will be virtual1, virtual2... etc.
